TEA5767 Radio Module FM Radio Module

TEA5767 Radio Module FM Radio Module is a high-sensitivity, single-chip electronically tuned FM stereo receiver designed for microcontrollers and DIY audio electronics. This compact board integrates the Philips/NXP TEA5767 IC, which completely eliminates external intermediate frequency (IF) tuning circuits. Consequently, it enables rapid prototyping and seamless I2C digital control with platforms like Arduino, ESP32, and Raspberry Pi. Furthermore, the onboard 3.5 mm audio jack allows direct output to headphones or external amplifiers. Therefore, developers can easily build intelligent, programmable broadcast receivers with minimal external hardware components.

Key Features:

• High Sensitivity: Integrates low-noise RF input amplifiers to achieve exceptional signal clarity across wide FM bands.
• Digital I2C Interface: Communicates via standard two-wire I2C protocol, allowing easy frequency tuning and status feedback.
• Integrated Tuning Circuit: Features automatic gain control (AGC) and software-controlled autonomous search tuning.
• Audio Output: Includes an onboard 3.5 mm stereo jack that connects directly to headphones or active speaker modules.
• Broad Reception Range: Covers global FM bands from 76 MHz to 108 MHz, including the Japanese and standard US/EU bands.
